background: the aim of the current study was to assess the mrna levels of two mitochondria-related genes, including nuclear-encoded nrf1 (nuclear respiratory factor 1), mitochondrial transcription factor a (tfam), and mitochondrial-encoded cytochrome c oxidase subunit 1 (mt-co1) genes in various stages of the human oocyte maturation. methods: oocytes were obtained from nine infertile women with...

it is now well established that the type la of serine/threonine protein phosphatases (pp1α) may be implicated in malignant phenotype. although the pp1α mrna level increased in livers at preneo-plastic stages of hepatocarinogenesis and all of examined rat ascites hepatomas, unexpectedly, dra-matically decreased in some of primary hepatomas. in order to elucidate the low level of pp1α mrna in som...

discussions in comparison to the control of wy14643, sandoz58-035, c9 and t11-cla, epa increased the pparα mrna levels (p = 0.024, p = 0.041, p = 0.043, and p = 0.004, respectively), even though, la had no significant effect on the pparα mrna expression (p = 0.489). materials and methods this experimental study investigated the effects of c9, t11-conjugated linoleic acid (c9, t11-cla). alpha li...

Polypyrimidine tract-binding protein 1 (PTBP1) and its brainspecific homologue, PTBP2, are associated with pre-mRNAs and influence pre-mRNA processing, as well as mRNA metabolism and transport. They play important roles in neural differentiation and glioma development. In our study, we detected the expression of the two proteins in glioma cells and predicted that they may be sumoylated using SU...

background: granuloca cells have a key role during estroeidogenesis. objectives: the purpose of this study was to determine the effect of number of culture medium granulosa cells on estradiol concentrations and mrna codding estrogenic and progestagenic enzyme. methods: briefly, follicles between 2 and 5 mm diameter were dissected from the ovaries of adult cows and were collected by rinsing the ...

Hydrogen sulfide (H2S) has been shown to protect the gastric mucosa through several protective mechanisms but till now its effect on mRNA expression of sodium bicarbonate cotransporter 1 (NBC1), trefoil factor1 (TFF1) and trefoil factor2 (TFF2) was not investigated. This study was aimed to evaluate the effect of H2S on mRNA expression of NBC1, TFF1 and TFF2 in rat gastric ...
